The world needs crazy inventors with wild dreams. While we might not long for the things that they create, their contraptions certainly make the day a little more enjoyable. Take the Carpool Deville as an example. Nobody (well, almost nobody) is asking for a hot tub fashioned from a 1969 Cadillac that is still drivable. But now that you know that such a beast exists, don't try to tell us you aren't at least intrigued.
